Abstract: PURPOSE:To enable easy manufacture of a pattern for a casting mold having an intricate shape in the stage of manufacturing said pattern for casting a member having an intricate three-dimensional curved surface by disposing a core material in a pattern body made of a flexible material and making the core material removable in the stage of forming a sand mold.

The material 4 is first removed after molding of a sand mold for casting and the body 3 is removed in succession, in the stage of forming said sand mold by using such pattern 2. Since the body 3 is made of the flexible material, said body shrinks by as much as the volume corresponding to the space made after the removal of the material 4; moreover, it deflects and therefore the pattern is extremely easily removed from the sand mold and the breakage of the sand mold is obviated.

Abstract: PROBLEM TO BE SOLVED: To emit hard X-rays suitable for developing a clear radiographic image by installing a tip projecting on the opposite side to a cathode in an anode side electrode of an electrode pair between which high voltage is applied for generating plasma by irradiation of laser beams to generate X-rays.

The photoelectrons 7 are concentrated on a needle- like tip 3a projecting on the cathode 2 side of the anode 3 to generate hard X-ray 8 having small radiation source diameter. The needle-like tip 3a of the anode 3 is preferably faced to the recessed surface of the curved cathode, plasma beams are efficiently converged to form a sufficient amount of hard X-rays.  A target for converging laser beams is separately formed from the anode 3, for example, by extending a part of the recessed surface of the cathode toward the anode 3 side, and although this is worn by abrasion, the shape and position of the tip 3a acting as the hard X-ray source are not changed.

Title: Optical bistable semiconductor laser
Inventor: WAKAO KIYOHIDE
IPC: H01S5/042
Filed: 1989-07-27
Abstract: PURPOSE:To increase an ON/OFF ratio by disposing a semiconductor optical amplifying element having a light emitting layer in an optical resonator and a semiconductor punchthrough element having a punchthrough layer for forming a potential barrier to be punched through in series, and using the through layer as part of an optical waveguide. CONSTITUTION:A semiconductor optical amplifying element 1 and a semiconductor punchthrough element 2 form one optical resonator 3. The element 2 has P-N junctions 11, 12 at both sides of a punchthrough layer 5b which is operated as functions of an optical waveguide layer and a potential barrier layer, and has a punchthrough control electrode 9 on its upper surface. When a voltage to be applied to the electrode 9 is increased, a depletion layer is elongated from the junction, and absorption coefficient alpha of the layer 5b is increased by Franz-Keldysh effect. However, when the applying voltage V is increased to a predetermined voltage, a current flows to the layer 5b due to erasure of a potential barrier, and the coefficient alpha is abruptly decreased. When a laser oscillation is generated by the switching of the coefficient alpha, the intensity of the light reciprocated between optical waveguides 5a and 5b is increased. Accordingly, the ON/OFF ratio of the optical output is increased.

CONSTITUTION:An N-type InAlAs clad layer 2, an absorption region 3 having quantum well structure consisting of InGaAs well layers 3a and GaSbAs barrier layers 3b, a P-type InAlAs clad layer 4 and a P-type InGaAs cap layer 5 are laminated and shaped onto an N-type InP substrate 1, and electrodes 6 and 7 are applied respectively onto the surface of the layer 5 and the rear of the substrate 1. According to such constitution, a barrier is formed only to either one of a conduction band or a valence band by the hetero-junction of the well layer 3a and the barrier layer 3b. That is, the layer 3b is formed to an N type when the barrier is shaped to the conduction band, the layer 3b is formed to a P type when the barrier is shaped to the valence band, and the impurity concentration of the layer 3b is made higher than the layer 3a in either case. Accordingly, electrons or holes are generated in the layer 3a by the confinement effect of the layer 3b.
